Many fisheries are successfully managed using reference points (RPs) based on the maximum sustainable yield (MSY), in particular fMSY , the fishing mortality rate that achieves MSY. Typically, fMSY is derived assuming fish are homogeneously distributed in space. However, fishing should be spatially allocated to optimize yields and reduce stock depletion, and fMSY should be derived assuming fish are heterogeneously distributed. In this thesis, we apply a deterministic, age-structured model to derive spatially-explicit MSY RPs....
